Metallurgical test work on a 60kg composite sample of Gabanintha mineralisation managed to develop a 99.53% pure vanadium pentoxide from an ammonium metavanadate precipitate that extracted in excess of 98% vanadium from a leach solution.

The leach solution had been formed from salt roasting the magnetic concentrate.

According to Technology Metals, the test work confirms its wholly-owned Gabanintha deposit can produce a high purity vanadium pentoxide from conventional processing methods.

Additionally, the high purity vanadium was created without further contaminant removal methods.

“To achieve greater than 99.5% purity of vanadium pentoxide from this phase of test work is a very exciting achievement for the company and I look forward to presenting these results to interested parties during my current visit to China,” Technology Metals managing director Ian Prentice said.

Technology Metals has now sent samples of the high purity vanadium to potential end-users for independent evaluation in multiple applications, including the steel and vanadium redox flow battery sectors.
